Context

Country: Canada
State/Province: British Columbia
Period: 1940's - ca. 2000's
Canada: Referenced in Dick Bourgeois-Doyle’s book, George J. Klein: The Great Inventor ~ Chapter 6: The Seeds of Snow, the objective Klein’s 1948 NRC research paper Canadian Survey of Physical Characteristics of Snow Covers: … to carry out periodic measurements of the physical characteristics of the snow-cover at a number of observation stations in order to obtain useful data applicable to a wide variety of winter problems, especially to those in which the condition of the snow is an important factor. The survey was intended to provide a basis for future studies of the fundamental properties of the various forms of fallen snow¹ . [see Supp. Info for the complete Canadian Context]
Function: A beam balance, bowl, and a conical 250cc soft snow cutting tool are used together to perform tests to determine the specific gravity, density of snow, and it’s free water content. The methods and instructions and technical function for using the Klein snow instruments as well as diagrams and photos can be found in Method of Measuring the Significant Characteristics of a Snow-Cover (1946) and Canadian Survey of Physical Characteristics of Snow-Covers (1950).
Technical: Lightweight, compact, durable and rust-proof instruments adapted for use in the field. A beam type balance chosen over a spring balance for it’s accuracy in cold temperatures. The 250cc soft snow sample cutting tool is designed to cut into the snowpack horizontally, rotated about it axis for removing a 250cc snow sample. The instruments were chosen for their ease of use and their design adapted for snow science research.
